What is Windmill?
Windmill is a fast, open-source alternative to platforms like Retool, Airplane, Superblocks, n8n, Airflow, and Temporal, designed to build comprehensive internal tools (endpoints, workflows, UIs). It supports coding in Typescript, Python, Go, Bash, SQL, or any Docker image, alongside intuitive low-code builders, featuring:
- An execution runtime for scalable, low-latency function execution across a worker fleet.
- An orchestrator for assembling these functions into efficient, low-latency flows, using either a low-code builder or YAML.
- An app builder for creating data-centric dashboards, utilizing low-code or JS frameworks like React.
Focus on code that matters: your critical business logic, from data transformation to internal API calls, starts as scripts and SQL files. Windmill transforms these into scalable microservices and tools without the usual heavy lifting.
An efficient runtime: execute code across languages with minimal overhead and instant starts.
While other frameworks offer pieces of what Windmill does, none combine its comprehensive feature set with full open-source accessibility. Whether compared to workflow engines like Temporal and Airflow or UI builders like Retool, Windmill stands out for its scalability, open APIs, and ease of use.
Windmill is an open-source, self-hostable platform that marries the flexibility of code with the speed of low-code solutions, enabling seamless automation of repetitive tasks.
